  • Patent number: 5384992
    Abstract: Garage extension apparatus comprising a pair of channel section guide tracks, one on each sidewall of the garage, and a movable structure formed of a roof, depending sidewalls and an up-and-over door. The structure is supported on a pair of ground engaging wheels, each mounted at the front of a respective one of the sidewalls by a screw jack, and on a pair of upper wheels which each run in the channel of a respective one of the guide tracks and which are pivotally mounted at the rear of the roof so that the movable structure can follow the slope of the carriageway, up or down, as it is drawn out of the garage. The screw jacks enable the movable structure to be levelled if the ground slopes from one side to the other.
